Which type of solar panel should you choose?

Types of solar panels

For many households, making the switch to solar energy is simple. After all, cutting back on your use of fossil fuels makes perfect sense. Unfortunately, comprehending the underlying science isn’t nearly that straightforward, and purchasing solar panels includes a number of technical phrases and ideas that we don’t frequently come across in our hectic daily lives. Solar power companies provide solar panels.

We recognize that you are interested in learning which solar panel type will provide the highest performance, lower your carbon footprint, and lower your energy costs. Mono, poly and thin film solar panels make up the majority of the solar panels used in home solar energy systems now available on the market. The type of solar panel is determined by the solar cells that make it up. Different solar panels are better suited for various scenarios since each type of solar cell has unique properties.

Three types of solar panels


The most advanced solar panel type among the three is monocrystalline. These panels are manufactured from monocrystalline silicon solar cells. The Czochralski method, by which a silicon crystal is fixed in a vat of molten silicon, is the method used to create these cells. The crystal is then gently and carefully removed, letting the molten silicon form into a crystal shell known as an ingot. A cell is made from the thin silicon wafers that are cut from this ingot. A solar panel is constructed using these cells.

Once fully developed, the monocrystalline cells have gaps between them that resemble squares without corners. Due to the presence of pure silicon in these solar cells, they will seem black; however, the frames and back sheets can be any color you like.


Polycrystalline solar panels are becoming more and more well-liked because of their effectiveness. Polycrystalline solar cells are created using a more recent technology, even though they still employ silicon like monocrystalline solar panels. In this process, bits of a silicon crystal are combined and added to a pot of molten silicon. The crystal is not gently removed, but rather allowed to break apart and cool. The silicon is divided into polycrystalline solar wafers and assembled into a panel after cooling in its mold.

Polycrystalline crystals will seem blue in color when subjected to sunlight. Fragmented silicon will have a paler, more bluish tint than pure silicon, which appears black in the sun. The panels made of polycrystalline material are square and have no gaps in between them.

Thin film

The humungous buildings are found to have the thin film solar cells. It is because they exhibit very low efficiency ratings. In such type of solar panels, a thin layer of a solar material (amorphous silicon (a-Si), copper indium gallium selenide (CIGS), and cadmium telluride (CdTe)) is being deposited onto a flat substrate. During manufacturing, the solar material condenses into a thin, light layer that is occasionally flexible.

What constitutes the PWRcell’s core elements?

During a utility power outage, the Generac PWRcell battery storage system can store solar energy to power your home and offer backup power. The majority of producers of household solar battery systems, including Tesla and Sonnen, use the same lithium-ion phosphate technology as the PWRcell. The chemistry of the PWRcell is identical to that of other batteries. The design is where the biggest distinction lies.

The Generac PWRcell home battery storage system is not only the most potent product on the market, but it is also the most adaptable and expandable solar battery. The new PWRcell battery module and optional Outdoor Rated (OR) PWRcell battery cabinet allow for fully outdoor installations in practically any setting. The Generac PWRcell energy storage system combines the industry’s best backup power and storage capacity with intelligent load control to deliver the first real full-home backup power and cost-saving solution.

Although the PWRcell is a sophisticated battery, mastering its potential can revolutionize how you manage energy in your house. It’s best to become familiar with every facet of the PWRcell if you’re thinking about it. The PWRcell can accomplish almost every work you require of it thanks to its battery cabinet, inverters, intelligence, management, and monitoring skills.

1.Battery cabinet

The PWRcell system’s central lithium-ion battery modules are kept in the PWRcell battery cabinet. Depending on the size of the needed backup power, the enclosure is made to accommodate any arrangement. The PWRcell system has the biggest capacity among residential and commercial batteries, and it allows you to expand an existing battery cabinet with additional battery modules to offer backup between the range of 9 kWh and a staggering 18 kWh. When your home’s energy consumption is subject to seasonal fluctuations, this scalability is crucial. To provide your project additional flexibility, the OR cabinet can be installed indoors or outside in any climate.


The solar array and batteries are integrated via the PWRcell inverter. With the ability to transform solar energy into electricity and then direct it, inverters serve as a sort of link between the solar system and the battery storage system. The inverter has a variety of user-selectable modes for regulating your energy. Depending on your home’s energy requirements, you can choose between battery backup power, self-supply, time-of-use, zero-import, and export-limiting modes.


A crucial component of the PWRcell that enables homeowners to effortlessly switch from the electrical grid to their whole-home backup power is an automatic transfer switch (ATS). Homeowners may then use their PWRcells to control how their solar panels are used, directing the energy they produce toward their most important systems or appliances.

Modules for smart management

To maximize a standby generator’s performance, Generac developed its Smart Power Management System. Up to 8 distinct Smart Management Modules (SMM) may be included in the system. The SMM modules function independently and are self-aware, in contrast to conventional load management systems that rely on additional control hardware.

Since frequency does not need taking into account changes in height, ambient temperature, or the type of fuel used in the generator, it is the best indicator of engine performance. The modules keep track of the frequency (Hz) of the electricity generated by Generac’s standby generators and, if it drops below a predetermined level, they automatically implement a power management mechanism to prevent the generator from being overloaded.

For loads that do not necessarily need to operate during an outage, the modules can be configured to a load priority between 1 and 8 or to a lock out only mode, which reduces the size of the generator required and results in a more affordable solution.

It merely records the incoming voltage and frequency. The circuit or device will be able to operate at the proper voltage and frequency thanks to the SMM. In the event that the voltage and frequency decrease to an undesirable level, the SMM will shut off the linked circuit or device. The SMM frequently carries heavier loads that are connected to the generator. In conjunction to the Load Shed Module in the transfer switch, the SMM aids in preventing an overload issue with the generator. The SMM has an outdoor-rated shell and offers a wide range of mounting possibilities. It can be mounted and put anywhere in between the circuit breaker and the energized item.

Solar panel performance type


Each PV panel’s efficiency varies due to numerous factors. This is also due to the property of a certain material to convert sunlight into electrical power. This allows for a range of silicon cell counts and types. The price, size, and weight can also be affected by the quantity of cells present in a solar panel. There is a widespread misperception that if a solar panel has more silicon cells, it will produce more high-wattage power. However, this isn’t always the case.

The average efficiency of solar panels used to be approximately 15%, but now it ranges from 15 to 22% as a result of advances in photovoltaic technology. Even close to 23% can be achieved by high-efficiency solar panels. As a result, a panel’s normal power rating is 370W, which is an improvement above 250W. Efficiency of photovoltaic (PV) cells and overall panel efficiency are two elements that affect the performance of solar panels.

Most effective: Monocrystalline

The best efficiency and power capacities of all panel types are often found in monocrystalline panels. Over 20 percent efficiency levels are possible with monocrystalline solar panels. Due to its efficiency as well as the fact that they are available in greater wattage modules, mono panels yield the maximum output. The power capacity of mono solar panels normally lies between 300 W and 400 W. In general, monocrystalline solar panels have 60 silicon cells per module, while there are also versions with 72 or 96 cells (usually for large-scale installations). Monocrystalline panels, however, are able to generate the maximum electricity even with the same number of cells.

Performance of a middle class: Polycrystalline

The second best efficiency and power capacities of all panel types are exhibited by polycrystalline panels. Typically, polycrystalline solar panels have an efficiency rating of 13% to 16%. Even if the difference between the two is only a few percentage points, when multiplied by the number of solar panels, it can add up to a significant amount. They are available in wattage modules lying in between monocrystalline and thin film modules.

The least effective: thin film

The thin film solar panels exhibit the least efficiencies and power capacity of all the solar panels. The efficiency of the cells will differ depending on the material employed, although it is often closer to 11%. Thin film technology does not come in standardized 60, 72, or 96 cell varieties like monocrystalline and polycrystalline solar panels, which do. Resultantly, the thin film’s physical size proves to be a major poer capacity determinant. In general, thin film panel technology will be outperformed in terms of power capacity per square foot by other two types of solar panels.

Kind of solar panel and price

Since installing solar panels might be expensive up front, many households do not make this choice lightly. Depending on the type of panel and how many are required for installation, monocrystalline solar panels are generally thought to be the most expensive option for solar panel installations. Solar panel installation costs can be recovered over time, but depending on a variety of variables, such as energy consumption and weather, this could take longer before you see a return on your investment.

Costliest: Monocrystalline solar panels

Solar panels made of monocrystalline technology are the costliest. But that doesn’t necessarily imply they aren’t the ideal choice for you. The silicon structure is the primary cost determinant. Single-crystal solar cells are more expensive due to the more complicated procedure required to generate monocrystalline panels, which requires the careful management of silicon solidification.

Mid-cost: Polycrystalline panels

Solar panels made of polycrystalline technology cost more than those made of monocrystalline technology, but less than thin film panels. But that doesn’t necessarily imply they won’t be your greatest selection. Molten silicon is poured into square molds by manufacturers to create polycrystalline panels, which are subsequently cut into individual cells by cutting the resulting wafers. This determines how much polycrystalline solar panels will cost.

Most affordable: Thin film panels

In comparison to crystalline solar panels, thin film panels are more affordable. Compared to conventional monocrystalline panels, these solar systems are more effective in low-light conditions because they are thin and flexible. Additionally, they are less intrusive than other types of solar systems and are simple to install. Different manufacturing processes are used to create thin film solar panels. To collect and transform energy, they don’t use crystals. It is determined by this element.

What is the best type of solar panel for your home?

Your decision about the kind of solar panel you select for your system will be heavily influenced by the specifics of your property and situation. Each form of solar panel has advantages and disadvantages, and the optimal choice will depend on your property’s conditions and the goals of your project.

Property owners with plenty of space for solar panels might save money up front by installing polycrystalline panels, which are less efficient and less expensive. If you are short on space and still want to maximize your savings, you can install high-efficiency monocrystalline solar panels.

Thin-film panels are generally used when installing solar hardware on a huge, home or commercial property that cannot withstand the increased weight of traditional solar equipment. On these kinds of roofs, thin-film panels’ lesser effectiveness can also be accepted because there is more room for them. For portable solar systems, such as those on RVs or boats, thin-film panels can occasionally be a viable alternative.

Other things to think about than solar panel type

At first, adopting this sustainable technology could seem intimidating. Planning is necessary to determine where to start. You might be curious about the price and how to choose the best panels for your style of home. Therefore, before beginning, be aware of these factors.

1.Power consumption

You must examine the electricity bill in order to determine the amount of power consumed at your residence. The amount of electricity used will be provided. If you can’t locate this value on your account, check your meter and deduct the prior reading by the most recent one. You ought to be prepared with your electricity usage.

Now you also desire daily or hourly consumption. Simply divide the monthly reading by 30 to get your daily power consumption if your electricity bill doesn’t show such an amount. To determine the number of panels you require, you need these values. Alternatively, you can take advantage of the installation services offered by the service provider firm; following these first calculations, they will assist you with everything.

2.Roof compatibility

The rooftop’s most exposed region needs to be identified through analysis. Solar panels generate more electricity the more sunlight they receive. Never allow any obstruction, including trees, buildings, or other structures, to stand in your way. As a result of them blocking the sun, the output will also be reduced.


You need to pay attention to how the panels are mounted if you reside in a windy area or a place where the weather has no chance. The energy flow may be disrupted by loose connections. Additionally, in high gusts, loose brackets can also cause the panels to fly away. You can put solar panels in your backyards if installing them on your rooftop is too unsafe or impractical. Additionally, before doing this, it must be confirmed if increased sunshine exposure is compatible.


You should think about the solar panel’s durability because the open environment will have an impact on it. The strength of the panels should be such that they can withstand extreme weather with ease. Alternately, if they are harmed or shattered, it will be a significant blow to your savings. In order to prevent future problems, it is necessary to negotiate long-term durability up front with the service provider.


You have a right to a warranty as a customer. It is advisable to talk with the service provider or firm about the appealing warranty period if you are making such a significant investment. By covering the costs in the event that the solar panel is damaged, it will assist you to maximize your investment.
